Aster plant named ‘Yomagic’

ABSTRACT

A new and distinct cultivar of  Aster  plant named ‘Yomagic’, characterized by its uniform, outwardly spreading and mounded plant habit; freely branching growth habit; dark green-colored foliage; uniform flowering habit; natural flowering season around September 11 th ; daisy-type inflorescences with dark purple-colored ray florets; and good garden performance.

Botanical classification/cultivar designation: Aster hybrida cultivar Yomagic.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Aster plant, botanically known as Aster hybrida and hereinafter referred to by the name ‘Yomagic’.

The new Aster is a product of a planned breeding program conducted by the Inventor in Leamington, Ontario, Canada and Alva, Fla. The objective of the program is to create or discover new potted Aster cultivars that have a uniform plant growth habit; good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, uniform flowering response and good postproduction longevity.

The new Aster originated from an open-pollination made by the Inventor in September, 1999, in Leamington, Ontario, Canada, of the Aster cultivar Sunny Almog, not patented, as the female, or seed, parent with a an unknown Aster selection, not patented, as the male, or pollen, parent. The new Aster was discovered and selected by the Inventor in January, 2001, as a single flowering plant from within the resulting progeny of the stated open-pollination grown in a controlled environment in Alva, Fla.

The selection of this plant was based on its uniform plant growth habit, good vigor and strong branching habit, numerous inflorescences, desirable inflorescence form and floret colors, uniform flowering response and good postproduction longevity.

Asexual reproduction of the new Aster by vegetative tip cuttings was first conducted in Alva, Fla. in March, 2001. Asexual reproduction by cuttings has shown that the unique features of this new Aster are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yomagic has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength, and/or light level, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Yomagic’. These characteristics in combination distinguish ‘Yomagic’ as a new and distinct cultivar of Aster:

-   -   1. Uniform, outwardly spreading and mounded plant habit.     -   2. Freely branching growth habit.     -   3. Dark green-colored foliage.     -   4. Uniform flowering habit.     -   5. Natural flowering season around September 11^(th).     -   6. Daisy-type inflorescences with dark purple-colored ray         florets.     -   7. Good garden performance.

Plants of the new Aster can be compared to plants of the female parent, the cultivar Sunny Almog. In side-by-side comparisons conducted in Alva, Fla., plants of the new Aster differed from plants of the cultivar Sunny Almog, in the following characteristics:

-   -   1. Plants of the new Aster were larger than plants of the         cultivar Sunny Almog.     -   2. Plants of the new Aster flowered about 10 to 14 days earlier         than plants of the cultivar Sunny Almog under natural season         conditions.     -   3. Plants of the new Aster had larger inflorescences than plants         of the cultivar Sunny Almog.     -   4. Plants of the new Aster and the cultivar Sunny Almog differed         in ray floret color as plants of the cultivar Sunny Almog had         dark pink-colored ray florets.

Plants of the new Aster can be compared to plants of the cultivar Purple Viking, disclosed in U.S. Plant Pat. No. 10,357. In side-by-side comparisons conducted in Alva, Fla., plants of the new Aster differed from plants of the cultivar Purple Viking in the following characteristics:

-   -   1. Plants of the new Aster were stronger and more rain tolerant         than plants of the cultivar Purple Viking.     -   2. Plants of the new Aster flowered about three or four days         earlier than plants of the cultivar Purple Viking under natural         season conditions.     -   3. Plants of the new Aster had smaller inflorescences than         plants of the cultivar Purple Viking.     -   4. Inflorescences of plants of the new Aster lasted longer than         inflorescences of plants of the cultivar Purple Viking.

Plants of the new Aster can also be compared to plants of the cultivar Judith, not patented. In side-by-side comparisons conducted in Alva, Fla., plants of the new Aster differed from plants of the cultivar Judith in the following characteristics:

-   -   1. Plants of the new Aster were more compact and more mounded         than plants of the cultivar Judith.     -   2. Plants of the new Aster flowered about five to seven days         earlier than plants of the cultivar Judith under natural season         conditions.     -   3. Plants of the new Aster had larger inflorescences than plants         of the cultivar Judith.     -   4. Inflorescences of plants of the new Aster had darker         purple-colored ray florets than inflorescences of plants of the         cultivar Judith.     -   5. Plants of the new Aster were more rain tolerant than plants         of the cultivar Judith.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs, following observations and measurements describe plants grown and flowered during the winter in Alva, Fla., in a polyethylene-covered greenhouse and under conditions which approximate those generally used in commercial potted Aster production. During the production of these plants, day temperatures were about 25° C. and night temperatures were about 18° C. Unrooted cuttings were directly stuck in 15-cm containers, exposed to long day/short night conditions, and pinched several times. At the time of the final pinch, photoinductive short day/long night treatments were initiated.
